Iryna Matsiakh
I am a Ukrainian born in a city that smells freedom, coffee, and chocolate. I love mountains and trees and would like to spend my life discovering nature and be helpful in forest protection.


Analyst of SLU Forest Damage Center

Researcher at SLU (from 1st of March 2022) under a new FORMAS grant No. 2021-01119: The fungal pathogen Lecanosticta acicola: A new threat to the native Scots pine in Sweden;

A postdoc at Swedish University of Agricultural Sciences, Southern Swedish Forest Research Centre, Alnarp, Sweden (2018; 2021);

Assistant Professor at the Forestry Department, the Ukrainian National Forestry University;

Apr 2019 –present: International expert (Forest protection division, national Forestry Agency of Georgia)

Associate Editor for the national journal "Forestry, Forest, Paper and Woodworking Industry" (NLTU, Ukraine)


2022 spring Sweden: "Broadleaves Forest dynamics, biodiversity and management for multiple-use"

2022 autumn-winter Sweden: distance course "Diagnos, förebyggande och hantering av biotiska skogsskador"; "Urban tree and Forest health"

Course module 3: Forest HealthMy teaching experience started in 2008 and it covers laboratory courses "Forest Entomology" and "Forest Phytopathology" for bachelors in "Forestry"; training practice "Forest Protection", laboratory course "Forest Entomology" for bachelors in "Horticulture"; laboratory course "Entomology" for bachelors in "Ecology"; laboratory course "Plant Protection"  and since 2018 course "Integrated protection of garden and park trees" for master’s students of the specialty "Garden and park economy".

2020-2021: for master’s students in "Horticulture" laboratory course "Integrated protection of horticultural plants" 

In October 2017, I had 8 lectures as a part of the teaching Program for international academic mobility Erasmus+ (direction KA1), Estonian University of Life Sciences, Tartu, Estonia. Forest Pathology, master course. 


My research range is related to forest pathology (tree diseases), partly forest entomology, and forest protection (prevention and control of tree diseases). Research activities are mostly concentrated on epidemiology, biological and ecological features of tree pathogens, their interactions with tree-hosts. I am curious about studying invasive pests and diseases in the forests and green areas, to learn new diagnostic tools for the detection and investigation of forest tree diseases (molecular techniques) with practical activities in the field (using biological control treatment) in order to ensure the sustainable development of forests for future generations. I am also in an ideal position to transfer the knowledge related to plant protection to students and forestry specialists. 

I have provided services and expert advice related to forest health in the form of courses for forestry specialists and consultation services to forest workers and quarantine personnel informal training, seminars, and on-site visits to the forest sector and other relevant stakeholders. 

I am responsible for practical training for foresters, NGOs, the local community, and interested stakeholders regarding phytosanitary conditions in chestnut forests affected by chestnut blight with particular emphasis on sanitary cuttings in the Zestaponi region (Georgia). 

From May 2021 I am Coordinating Leader of two national projects on protected areas in Borjomi-Kharagauli National Park and Kolkheti National park in Georgia related to management in heavily damaged pine forests and oak decline (full responsibility on logistics, funding management, communications, reporting, workshops, field staff training, field and laboratory work).

2022, Dr. habil. Forestry, Biological Science, the Ukrainian National Forestry University

2013, Ph.D. Forestry, the Ukrainian National Forestry University. Discipline/Scientific Field: forestry, forest plant pathology

1997-2002: Student, the Ukrainian National Forestry University (Degree: specialist in forestry and horticulture)


Currently, I am the main supervisor of 1 Master's student and co-superviser of 1 PhD student in Sweden.  Previously I have supervised 16 undergraduate students as the main supervisor and co-supervisor (7 Masters and 10 Bachelor) and 1 internship student on short-term research stay (Lublin University, Poland) as the main supervisor.
